Montego AWD V6-3.0L VIN 1 (2005)
K1
K2-K3
Normal Operation
The DVD player communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits 2180 (WH/BK) and 2181
(BK/YE). The medium speed CAN remains operational with the severing of one of the medium speed CAN circuits or if the data minus circuit is
shorted to ground. Communication may also continue if one of the termination resistors is lost. The medium speed CAN does not remain operational if
the data plus circuit is shorted to ground or shorted to voltage. The medium speed CAN also does not remain operational if the data minus circuit is
shorted to voltage. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the
medium speed CAN circuits, damage to the data link connector (DLC) C251, damage to the DVD player connector, or damage to an in-line connector.
